I've recently seen a few image only answers, which just take a screenshot of the book and post them as answers. My initial thought was that we need to utilize OCR to convert images to text and then add them in the answers.

Text instead of images have many advantages:

• Few of us use textbased browsers (Lynx) which do not render any images.
• Few of the users might be partially blind and use screen readers. The screen readers read out the image URL, which is not quite helpful.
• Text would make the post more searchable.

Given all these, would it be possible to have a small rule which states that images should be converted to text, where possible? (I know that there are a few non-English texts which are not convertable using OCR, but then again, we are an English site. non-English text images would be acceptable provided the poster has added the translated version as text)
